Environmental systems and management activities on the Kennedy Space Center, Merritt Island, Florida: results of a modeling workshop
David B. Hamilton, Austin K. Andrews, Gregor T. Auble, Richard A. Ellison, Adrian H. Farmer, James E. Roelle
1985, Report
In the early 1960's, the National Aeronautics and Space Administration (NASA) began purchasing 140,000 acres on Merritt Island, Florida, in order to develop a center for space exploration. Most of this land was acquired to provide a safety and security buffer around NASA facilities. NASA, as the managing...
Variability in measured bedload-transport rates
William P. Carey
1985, Journal of the American Water Resources Association (21) 39-48
Variability in bedload-transport rates during constant water discharge is an inherent part of the bedload-transport process. Although this variability has been measured extensively in the laboratory, similar information generally is not available from field measurements. During a four-day period of nearly constant water discharge, four sets of consecutively collected bedload...
Two-million-year record of deuterium depletion in Great Basin ground waters
Isaac J. Winograd, Barney J. Szabo, Tyler B. Coplen, A.C. Riggs, Peter T. Kolesar
1985, Science (227) 519-522
Fluid inclusions in uranium series-dated calcitic veins from the southern Great Basin record a reduction of 40 per mil in the deuterium content of groundwater recharge during the Pleistocene. This variation is tentatively attributed to major uplift of the Sierra Nevada Range and the Transverse Ranges during this epoch with...
Variations in the global carbon cycle during the Cretaceous related to climate, volcanism, and changes in atmospheric CO2
M.A. Arthur, Walter E. Dean, S.O. Schlanger
1985, Book chapter, The carbon cycle and atmospheric CO2: Natural variations archean to present
The stratigraphic record from both deep-sea and shallow-water depositional environments indicates that during late Aptian through Cenomanian time (1) global climates were considerably warmer than at present; (2) latitudinal gradients of atmospheric and oceanic temperatures were considerably less than at present; (3) rates of accumulation of organic matter of both...
Water resources of north-central Iowa
Robert Buchmiller, Gary Gaillot, P. J. Soenksen
1985, Iowa Geological Survey Water Atlas 7
One of man's fundamental needs is water. Modern man needs both a safe and dependable supply of water to maintain his present economic, industrial, and cultural level. In order to use this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of water sources, and...
Uptake, biotransformation, and elimination of rotenone by bluegills (Lepomis macrochirus )
W.H. Gingerich, J.J. Rach
1985, Aquatic Toxicology (6) 179-186
Yearling bluegills (Lepomis macrochirus) were exposed to sublethal concentrations of [14C]rotenone (5.2 μg/l) for 30 days in a continuous flow exposure system and then transferred to clean, flowing water for an additional 21-day depuration period. Rates of uptake and elimination and profile of the rotenoid metabolites in head, viscera, and...
Mapping and research in the exclusive economic zone
Bonnie A. McGregor, Millington Lockwood
1985, Report
By proclamation of the President on March 10, 1983, the United States claimed sovereign rights and jurisdiction within an Exclusive Economic Zone (EEZ). The United States is responsible for wisely developing and managing the EEZ and its marine resources and for protecting its environment. The U.S. Exclusive Economic Zone is...

Hydrogeology, digital solute-transport simulation, and geochemistry of the Lower Cretaceous aquifer system near Baltimore, Maryland
Francis H. Chapelle
1985, Maryland Geological Survey Report of Investigations 43
This study was made to develop information on the hydrogeology and ground-water geochemistry of the Patuxent and Patapsco aquifers (Lower Cretaceous) near Baltimore, Maryland. This information is needed to evaluate the availability and chemical quality of water from these aquifers.The Patuxent aquifer unconformably overlies Lower Paleozoic and Precambrian basement rocks...
Chronology of migration by American coots in Oklahoma
William R. Eddleman, Fritz L. Knopf, Craig T. Patterson
1985, Journal of Wildlife Management (49) 241-246
American coots (Fulica americana) were studied on large reservoirs in north-central Oklahoma in 1979-1982 to determine chronologies of migrations by age- and sex class. Coots began migrating into Oklahoma in mid-September, numbers peaked in early to mid-October, and few birds were seen after 1 November. Some late migrants...

Geomorphologic evidence for ground ice on Mars
Baerbel K. Lucchitta
1985, Book chapter, Ices in the solar system
For ground ice to exist on Mars, two conditions have to be met. One is the presence of permafrost; the second is the availability of water. Because the mean temperature of Mars’surface is − 80 C., permafrost 1–3 km thick occurs over the entire planet. Remote-sensing measurements suggest that water...

National water summary 1984: Hydrologic events, selected water-quality trends, and ground-water resources
U.S. Geological Survey
1985, Water Supply Paper 2275
Water year 1984 was a year of extreme hydrologic conditions. For the third consecutive year, precipitation and resulting runoff were well above long-term averages in most of the Nation and as much as 400 percent above average in the Southwest. National flood damages during the year were the third highest...

Edward H. Brown Jr., Ronald W. Rybicki, Ronald J. Poff
1985, Technical Report 44
This paper examines the population dynamics of the bloater (Coregonus hoyi) in Lake Michigan during a progressive decline in abundance from about the mid1960s through the mid1970s, and during a subsequent recovery that is still underway. The study focused on developing a data base and methodology for projecting fishable surpluses,...
